“This is the next generation but it doesn’t completely replace the older one,” said Martin Southam, director of marketing. “It has a lot more functionality but not all customers might need that, and they might be happy with the older models.
“We’ve made it smaller and more powerful than previous generations. The power density is 33% higher than any competitor product. We’ve also significantly reduced the weight and the overall size so it’s up to 50% lighter than the competition.”
Housed in a 483mm wide rack package, the units are said to address a broad market, including component, aerospace and automotive testing, semiconductor fabrication, medical imaging, water treatment, plating and solar array simulation.
Using digital signal processing technology, five voltage models are available: 0-10V/500A, 0 20V/250A, 0-30V/170A, 0-300V/17A and 0-600V/8.5A. The units can operate in constant current, constant voltage or constant power modes, and offer internal resistance simulation.
They can accept three-phase 170 to 265V AC, 342 to 460V AC or wide range 342 to 528V AC inputs, with active power factor correction.
In addition to doubling the power density over the existing Genesys 5kW 2U series, the Genesys+ offers faster up and down programming response times speed up operation with user adjustable voltage and current slew rate control.
Arbitrary waveform profiles, such as car battery simulation at vehicle start up, of up to 100 steps can be generated.
A new advanced parallel master/slave system is said to allow a multi PSU system to achieve dynamic response and ripple and noise performance comparable to that of a single power supply. Up to four Genesys+ units can be connected in parallel with a single data link cable between units.
“In addition we have ‘0 stacking’, without any power de-rating,” Southam added.
According to the company, other 1U products tend have air inlets along the side of the casing as well as the front which can complicate air cooling in a rack. The Genesys+ doesn’t have or need any side air inlets and can therefore be zero stacked regardless of the rack design.
The series is compatible with both the TDK-Lambda Genesys and Z+ models. All functions can be programmed via the front panel or remotely using the LAN (LXI 1.5), USB 2.0 or RS232/485 communications interfaces.
The Genesys+ design incorporates the Anybus CompactCom interface platform to convert emerging standards, such as Devicenet, Ethercat, Modbus and Profibus.
